Question

我有自己的自定义Spring Data公共存储库，以便为所有Spring Data存储库提供通用行为。我只需要在创建存储库时修改EntityManager。但由于bean是通过new运算符创建的，因此无法将Spring bean注入JpaRepositoryFactoryBean。

public class BasicJpaRepositoryFactoryBean<T extends Repository<S, ID>, S, ID extends Serializable> extends JpaRepositoryFactoryBean<T, S, ID> {

 @Autowired
 private SomeService service; // - it does not work 

  @Override
  protected RepositoryFactorySupport createRepositoryFactory(EntityManager em) {
    // do some logic here
    service.doSmth();  
    return new CommonRepositoryFactory<>(em);
  }

  private static class CommonRepositoryFactory<T, I extends Serializable> extends JpaRepositoryFactory {

    private final EntityManager em;

    public CommonRepositoryFactory(EntityManager em) {
      super(em);
      this.em = em;
    }

    @SuppressWarnings("unchecked")
    protected Object getTargetRepository(RepositoryMetadata metadata) {
      JpaEntityInformation entityInformation = getEntityInformation(metadata.getDomainType());
      return new CommonRepositoryImpl(entityInformation, em);
    }

    protected Class<?> getRepositoryBaseClass(RepositoryMetadata metadata) {
      return CommonRepositoryImpl.class;
    }
  }

}

在该类中实现一个setter或从中扩展一个setter。
